VERY CONFUSED over Eevee Light’s shadow generation from a Bake Indirect Lighting perspective.
Ok, during the old OLD days of the scanline renderer, I understand why we need lights that INSIST on generating its own shadows, that makes sense since there are not global illumination/path tracing involved.
When doing outdoor scene in Eevee without the need to press the “Bake Indirect Lighting” button [without the need for irradiance volume], yes, checking the Shadow and Contact Shadow makes sense.
BUT BUT BUT !!!
For indoor scene when we are using the irradiance volume and the “Bake Indirect Lighting” button, isn’t/shouldn’t the various shades of shadow derived MERELY from the various absent of light in an area ?
Just like path tracing renderers, lights that needs to forcibly artificially “create” a shadow makes no sense because the indirect lighting will hereby CREATE the actual REAL shadows.
Doesn’t having lights in Eevee generating its own shadow in an interior scene where irradiance volume already calculated the bounce light kind of “doubling” the shadow effect which shouldn’t be ?
Very confused about the usage of light shadows in indoor lighting in Eevee, please someone explain this to me.
Should we even turn light shadow on for indoor with bake indirect already turned on ?
